Intelligence
Built to an uncompromising standard, exposing hostile intent, anticipating the next move, and outmaneuvering the most capable nation-state adversaries by turning raw noise into advantage long before they strike.
Hello and こんにちは!
I am Scott Jarkoff (ジャーカフ スコット),
a threat intelligence and cyber security professional, entrepreneur, visionary leader, presentation virtuoso, cyclist, tech geek, and wannabe iPhone photographer living and working in the heart of Tokyo, Japan.
a powerhouse on-stage speaker, delivering electrifying and profoundly impactful keynotes that captivate, challenge, and inspire.
a remarkably creative presenter featuring incredible visuals combined with striking insights on cyber threat actors, their evolving tradecraft, and the attacks defining modern cyber warfare. I illuminate the future of generative AI in offensive operations, the shifting cyber security landscape, and the critical thought leadership shaping the next era of digital conflict.
I write about cyber security, sophisticated cyber adversaries, global cyber attacks, threat intelligence, the eCrime ecosystem and the dark web economy, leadership, global and domestic travel, hiking trips in Japan, and occasionally post various photos taken with an iPhone and meager composition skills.
I am the ambitious co-founder and mastermind behind deviantART, the largest and most vibrant online art community the world has ever seen, launched on August 7, 2000.
I am orchestrating the inception of Praeryx, a new cyber threat intelligence startup currently in deep development.
the quiet architect of jark after dark, a nocturnal pursuit of the uncomfortable questions hiding behind polished narratives, built for those who suspect the official story is never the whole one.
Finally, I live in Tokyo, Japan, where I architect and oversee these mission critical operations.
Reach out to me for inquiries.
Three decades across government and industry have forged a rare command of cyber security and threat intelligence. My experience spans technology and code, entrepreneurship, and the global stage. I have written software, scoured security logs, administered firewalls, and architected defense-grade systems. I have built companies, led exceptional teams, and directed regional intelligence strategy. I translate complex cyber realities into language understood from the engineering floor to the boardroom and the halls of government. In today’s sophisticated threat landscape, the ability to decode chaos into clarity and transform understanding into decisive action is not optional. It is imperative.
Built to an uncompromising standard, exposing hostile intent, anticipating the next move, and outmaneuvering the most capable nation-state adversaries by turning raw noise into advantage long before they strike.
Exceeding expectations is only the baseline. I build and lead elite teams where innovation thrives, collaboration becomes a force multiplier, and elegant solutions achieve what others consider impossible.
Co-founder of deviantART and Praeryx, developing and building ambitious ventures, challenging established industries, and transforming revolutionary ideas into platforms, companies, and global communities with lasting impact.
Electrifying keynotes and commanding panel conversations exposing the forces reshaping cyber conflict, shattering conventional thinking, and leaving audiences with a radically clearer view of what comes next.

Airbnb charges like a hotel and then hands you the cleaning. For the travel most people actually do, solo, short, and for work, the front desk wins on price, trust, and loyalty, and Airbnb only drew the line when it got caught.

The FBI has formally named North Korea for the US$6.3 billion Binance theft, the largest in history, confirming an attribution the tradecraft already pointed to. One question is answered. How the attacker turned Binance’s own signing systems against it is not.
NIST built ML-KEM to protect the world’s data from a future quantum computer. North Korea’s Lazarus found an advantage in the present, running the same post-quantum mathematics inside operational malware before most enterprises have migrated. The standard did not fail. It worked for the wrong side.
North Korea stole US$6.3 billion from Binance in roughly twenty minutes, the largest cryptocurrency theft in history. No private key had to leak. The attacker seized the machinery turning Binance’s intent into valid signatures, and ten blockchains moved as one.
For years, the surveillance state called metadata harmless. Icepick turned DHS’s own identity graph against it, linking 39 HSI employees to certified undercover operation groups and showing how ordinary administrative structure can expose covert work no secret roster ever had to name.
Airbnb charges like a hotel and then hands you the cleaning. For the travel most people actually do, solo, short, and for work, the front desk wins on price, trust, and loyalty, and Airbnb only drew the line when it got caught.
OpenAI set its own frontier agents loose on its training environment, and they broke out. The more unsettling finding was that the same systems could reach the record meant to catch them.
A Russia-aligned group held a Ukrainian grain company for weeks, then handed it to VOODOO BEAR for the wipe. The weapon was Microsoft’s own tooling, pushed through the victim’s own Active Directory.
Everyone wants attribution to end in proof. It never does, and the analysts most certain they have a name are the ones most easily played. Naming an adversary is a discipline of graduated confidence, worked against an enemy who builds the evidence to deceive. Seven myths, taken apart.
The FBI says an OpenAI engineer bugged its most sensitive conference room with a fourteen-dollar board, then booked a one-way ticket to Riyadh. The breach never touched the network. A frontier lab’s most valuable asset is the person who badges in, and the simplest way to take it is recruitment.
A GRU actor spent two months inside a NATO naval shipbuilder, reached a law enforcement agency and an aircraft engine maker alongside it, and did it with a Word macro and off-the-shelf tools. The prize was never the fleet. It was the industrial base deciding how fast the alliance can rebuild.
